What is the value of y?

horrorfan [7]

Answer:

y = 25

Step-by-step explanation:

Hey There!

The angle labeled x is supplementary to the angle that is equal to 115 meaning that the sum of the two angles will add up to equal 180

so to find x we subtract 115 from 180

180-115=65 so x = 65

Now we can find y

remember the sum of the triangles angles add up to equal 180

so we subtract the given angles(90 and 65) from 180

180-90-65=25

so y = 25

Find the surface area of the prism formed by the net

Lunna [17]

ANSWER

$T.S.A=1960m^2$

EXPLANATION

The diagram represents the net of a rectangular prism.

The dimensions are,

$l=42m$

$w = 14m$

and

$h = 7m$

The total surface area of a rectangular prism is given by:

$T.S.A=2(lw + lh + wh)$

We substitute the values to obtain,

$T.S.A=2(42 \times 14 + 42 \times 7 + 14 \times 7)$

$T.S.A=2(980)m^2$

$T.S.A=1960m^2$
